Abstract

The utility model discloses a thread-trimming foot lifting-pressing device of a reinforcing stitch sewing machine, which comprises a machine head, wherein a motor seat is fixed at the front end of the machine head, a stepping motor is fixed at one side of the motor seat, a thread-trimming crank is flexibly arranged at the other side of the motor seat and provided with a thread-trimming crank ball at the end, a thread-trimming groove cam and a foot lifting-pressing cam are sequentially sheathed on an output shaft of the stepping motor, the thread-trimming groove cam is provided with an inner rolling groove, the thread-trimming crank ball is arranged in the inner rolling groove and can annularly roll along the inner rolling groove, and the foot lifting-pressing cam is connected with a foot lifting-pressing crank connecting rod by a foot lifting-pressing crank shaft. In the utility model, as the thread-trimming groove cam and the foot lifting-pressing cam are separately arranged, the thread-trimming foot lifting-pressing device is easy to process and convenient in installation. By adopting the thread-trimming foot lifting-pressing device, the numerical value of thread-trimming and foot lifting-pressing can be convenient to adjust, and the goal that the length of the thread end as well as the time and the height of foot lifting-pressing are independently controlled when the thread is trimmed is achieved, which is beneficial for improving the control accuracy of the thread-trimming and the foot lifting-pressing.

Description

Reinforce seam sewing machine thread-trimming lifter-presser foot device
Technical field
The utility model relates to the sewing machine technique field, especially a kind of reinforcing seam sewing machine thread-trimming lifter-presser foot device.
Background technology
Reinforce seam sewing machine and be a kind of need reinforcement seam and have the Sewing machines of pattern repeat seam among a small circle such as clothes case and bag that is used for,, have accurate localization, functions such as presser foot lifter, automatic shearing automatically by computer program control.The presser foot lifter and the used cam of trimming of similar products at home and abroad have adopted same part at present, by console presser feet and the trimming action simultaneously of a cam link mechanism, this version, its weak point is to install comparatively trouble of location, presser foot lifter cam and trimming cam can't be adjusted respectively, realize difficulty of precision control ratio.
The utility model content
The technical problems to be solved in the utility model is: overcome the deficiency in the prior art, a kind of reinforcing seam sewing machine thread-trimming lifter-presser foot device is provided, can't adjust respectively to solve on the present reinforcing seam sewing machine presser foot lifter cam and trimming cam, the precision control ratio is the problem of difficulty.
The technical scheme that its technical problem that solves the utility model adopts is: a kind of reinforcing seam sewing machine thread-trimming lifter-presser foot device, comprise head, the head front end is fixed with motor cabinet, motor cabinet is fixed with stepper motor on one side, the another side is provided with the trimming crank that the end has trimming crank ball, be set with trimming grooved cam and presser foot lifter cam on the output shaft of stepper motor successively, the trimming grooved cam has interior slot rolling, trimming crank ball is positioned at described slot rolling and can rolls along the slot rolling annular, and the presser foot lifter cam is connected with the presser foot lifter crank connecting link by the presser foot lifter crank axle.
Specifically, described trimming crank middle part is provided with the crank cover, is fixed with crank ball axle on the motor cabinet, and crank cover turning set is on crank ball axle; Described presser foot lifter cam fixes by fixed axis and trimming grooved cam.
The beneficial effects of the utility model are: the utility model separates setting with the trimming grooved cam with the presser foot lifter cam, processing is simple, be convenient to install, can conveniently adjust the numerical value of trimming and presser foot lifter, the purpose of the height of the time of the end of a thread length, presser foot lifter and presser foot lifter when realizing regulating trimming separately, thus help improving the control accuracy of trimming and presser foot lifter.

The specific embodiment
In conjunction with the accompanying drawings the utility model is further described now.The schematic diagram that these accompanying drawings are simplification only illustrates basic structure of the present utility model in a schematic way, so it only shows the formation relevant with the utility model.
As Fig. 1~a kind of reinforcing seam sewing machine thread-trimming lifter-presser foot device shown in Figure 4, comprise head 1, be fixed with motor cabinet 2 at head 1 front end, be fixed with stepper motor 3 on wallboard one side of motor cabinet 2, the output shaft of stepper motor 3 passes the wallboard of motor cabinet 2, the another side of the wallboard of motor cabinet 2 is provided with trimming crank 5, be equipped with crank cover 10 at trimming crank 5 middle parts, be fixed with crank ball axle 11 on the wallboard of motor cabinet 2, crank overlaps 10 turning sets on crank ball axle 11 and trimming crank 5 can be rotated around crank ball axle 11, be fixed with trimming crank ball 4 in the end of trimming crank 5, be set with trimming grooved cam 6 and presser foot lifter cam 7 on the output shaft of stepper motor 3 successively, this presser foot lifter cam 7 fixes by a fixed axis 12 and trimming grooved cam 6, after presser foot lifter cam 7 is sleeved on the output shaft of stepper motor 3, available dog screw is adjusted to correct angle position with it, the interior slot rolling 60 that on trimming grooved cam 6, has an annular, trimming crank ball 4 is positioned at described slot rolling 60 and can makes annular along slot rolling 60 and roll, thereby drive trimming crank 5 and do corresponding oscillating motion, thereby make on the Sewing machines and cut off the end of a thread with the blade of trimming crank 5 interlocks, presser foot lifter cam 7 then is connected with presser foot lifter crank connecting link 9 by presser foot lifter crank axle 8, motion by presser foot lifter cam 7 drives the corresponding swing of presser foot lifter crank connecting link 9 dos, realizes that the height of sewing-machine foot is regulated.
The utility model separates setting with the trimming grooved cam with the presser foot lifter cam, processing is simple, save material, reduced the requirement that is associated between the single part, be convenient to install, the more important thing is and an original cam is controlled trimming simultaneously and two actions of presser foot lifter are separated, can conveniently adjust the numerical value of trimming and presser foot lifter, the end of a thread length, the time of presser foot lifter and the height of presser foot lifter when realizing regulating trimming separately, thus help improving the control accuracy of trimming and presser foot lifter action.
Above-mentioned embodiment only is explanation technical conceive of the present utility model and characteristics; its purpose is to allow the personage that is familiar with this technology can understand content of the present utility model and is implemented; can not limit protection domain of the present utility model with this; all equivalences of doing according to the utility model spirit essence change or modify, and all should be encompassed in the protection domain of the present utility model.
